java

I wanted to try making a home surveillance project using my webcam and EV3 sending images into Dropbox. But how to put the obvious time and date stamp on the images? It turns out this is really easy to do using the Graphics2D Java class! A short tutorial on how to do this…

This project presents a leJOS class to interface with the NXTBee, along with some sample Java code in leJOS showing how to send and receive data. I’ve written extensively about the Dexter Industries NXTBee sensor before. The NXTBee provides long-range serial wireless communication for the Lego Mindstorms NXT.
